How can the gallonage output of a sprayer be decreased?

Decreasing the RPMs of the sprayer motor is an effective method for reducing the gallonage output of a sprayer. When the RPMs are lowered, the pump operates at a reduced speed, which in turn decreases the flow rate of the liquid being applied. This means that less pesticide is being delivered per unit of time, thereby lowering the overall output in gallons.

In this context, other methods such as decreasing the speed of travel or increasing the nozzle size could lead to different outcomes. Slowing down the speed of travel may allow for a more concentrated application over an area without actually reducing the gallonage per minute released by the sprayer. Meanwhile, increasing the nozzle size typically results in a higher flow rate, which would increase the output rather than decrease it. Lastly, increasing the pressure usually forces more liquid through the nozzle, which again would increase the gallonage output instead of decreasing it.
